The present Experimental investigation is to study the Mechanical Properties of the Fly ash concrete reinforced with steel fibers. The concrete composite comprises of steel fibers in different percentages and partial replacement of cement in different proportions. Steel fibers varied from 0%, 0.5%, 1% and 1.5% by weight of cement and replacement of fly ash varied from 0%, 10%, 20%, 30% and 40% ...

Experimental studies on basalt fiber have been performed in China and abroad. Specifically, the compressive properties, flexural properties, splitting tensile properties and impact test behavior of chopped basalt fiber-reinforced concrete have been investigated. In addition, the effects of the mixing amount of fibers on the mechanical properties of C30 concrete were scrutinized, and the best mi...

Abstract—In this study, the effects of waste marbles as aggregate material on workability and hardened concrete characteristics of self compacting lightweight concrete are investigated. For this purpose, self compacting light weight concrete are produced by waste marble aggregates are replaced with fine aggregate at 5%, 7.5%, and 10% ratios. Fresh concrete properties, slump flow, T50 time, V fu...

Steel fiber reinforced self-compacting concrete is well accepted for better resistance segregation, and effective use in congested reinforcements. It will have improved ductile property crack propagation minimum. As the need sustainable materials increasing all over world, innovative technique making more durable significant importance. prone to cracking, cracks make vulnerable fact that it deb...

This paper reviews recent research on the application of an engineered cementitious composite (ECC) as overlay in the repair of deteriorated concrete structures. ECC is an ultra-ductile fiber reinforced cement based composite, that has metal-like features when loaded in tension. The uniaxial tensile stress-strain curve shows a ‘yield’ point, followed by strain-hardening up to several percent st...

Carbon fiber reinforced polymer (CFRP) sheets are externally bonded to reinforced concrete (RC) members to provide additional strength such as flexural, shear, etc. It has been widely accepted that carbon fiber reinforced polymers (CFRPs) can be used effectively to strengthen reinforced concrete (RC) members. This paper is intended to study and use externally bonded CFRP strips to repair and st...

Estimating mechanical properties of concrete before designing reinforced concrete structures is among the design requirements. Steel fibers have a considerable effect on the mechanical properties of reinforced concrete, particularly its tensile strength. So far, numerous studies have been done to estimate the relationship between tensile strength of steel fiber reinforced concrete (SFRC) and ot...

Three-point bending tests on notched beams of three types of steel fiber-reinforced self-compacting concrete (SFRSCC) have been performed by using both a servo-hydraulic machine and a drop-weight impact instrument. The lo ading rates had a range of six orders of magnitude from 2.20 × 10-3 mm/s (quasi-static) to 2.66 × 10³ mm/s. These SFRSCCs had the same matrix, but various types of steel fiber...

Steel fiber reinforced self-compacting concrete (SFRSCC) inherits the advantages of (SCC) characterized by sound fluidity and self-compaction. Meanwhile, addition steel has enhanced roughness ductility substratum. This paper designs SCC two different strength grades, including C40 C60, conducts SFRSCC quasi-static mechanical property test split tensile test. Uniaxial is carried out through desi...

During recent years, the use of fiber-reinforced polymers (FRP) as a desirable alternative for improving the behavior of lateral resisting system are known. There are various factors influencing the quality of such kind of rehabilitation. This study aims to investigate the influence of geometric characteristics and arrangement of FRP layers on rehabilitating of concrete shear walls.  A few rein...
